CHEMICAL TOILET.

Application filedv April 16, 1928. SeralNo. 270,40?.

I This invention relates to a chemical toilet for use in homes, schools, factories and other buildings or places where such an equipment maybe necessary or desirable and involves theuse of areceiving tank or receptacle adapted to be installed in the ground, mainly below the surface thereof and provided with means for receiving a suitable drop tube to which the closet bowl is operatively connected, the `tank being provided with a suitable outlet leading to a subsurface hygienic drain pool or other reposi-y j tory. v

The main object is toy provide a more sanitaryand convenient apparatus' of this character than has heretofore been practised by constructing the tank and all parts carried thereby or therein as al unitary article of manufacture exclusive of the bowl in such manner that the liquid therein will automatieally seal all of the inlet openings leading thereto to prevent the escape of Vvitiated Another object lis to provide overflow means communicating with the 'outlet of the tank for automatically regulating the levell of the liquid in said tank. y

A further object is to provide the overflow tube or bafflewith a suitable valve controlling the outlet in the bottom of the tank and to enable the overflow tubeV with the valve thereon to be raised. and lowered for openingand closing the outlet when desired.

Another object is to providel the top of the tank with a manhole tube rigidlysecured thereto to forma gas and liquid tight joint therewith and adapted to extend upwardly therefrom above the 'surface of the ground and also into the tank below the normal level of the upper end of the overflow tube so that the liquid will seal the opening in the lower end of the manhole tube around the upper end of the overflow tube.

Another .object is to provide movable meansV within the manhole tube and operatively connected to the overflowtube for raising and lowering the latter and the valve carried thereby to open and "close the outlet in the bottom of the tank at will.

Another object is toprovide the interior of the tank with an agitator having a stem'l extending upwardly through a tubular guide i l inthe tube of the tank where it is vaccessible for operationat will and to extend theguideY will) tube into the tank below the level ofthe liquid therein so that the liquid may form a gas tight joint therewith. l Y

A further Objectis to provide the top of the tank with a guidetube securedthereto to form a liquid-tight'joint therewithA for receiving the lower end of the drop tubev leadingfrom the closet bowl and to extend the tubular guide below the level of the liquid in ytherewith to prevent the escape of vitiated air or gas through the drop tube.

Other objects and uses relating to specific parts of the apparatus will be brought out in the following description.

In the drawings Figure l is a longitudinal `vertical sec# tional-'view ofv achemical toilet apparatus involving the various features of our inven- 'Figure 2 is an' enlarged horizontalv sectional view inverted Vthrough the upper end of the manhole tube taken on line 2 2, Fig-A ure 1,show1ng the operating means for the overflow tube and valve carriedthereby.

As illustrated, this apparatus Acomprises` -a horizontally elongated tank or receptacle 1 adapted to be installed mainly beneath the surface ofthe ground lt so as to eX# tend partially at the outsidev and partiallyat the inside of a building wall B The inner endof the tank is provided with a tubular guide 2 secured in an for receiving an upwardly extending drop opening inr the Atop lwall thereof to form a u liquid-tight joint therewith and.v extended rsome distance above and below said top wall tube 3 which is also secured in an open-Y l ing in the upper end of the guide tube 2 to form an lair and gas tight joint therewith. ,j

This drop ytube 3 extends a relatively short distance 'below the upperend of the guide tube 2 and also extends upwardly to a superposedfloor F upon whiehis mounted a closetv bowl Q having its lower end connected to the'uqiper end Aof lthe I drop tube in any well-known manner to form an air and gas tightjoint therewith.

The outer end of the tank is provided with f a manhole tube 4 vvhich is secured in an opening in the `top wall thereof to form a gas extended'V above the ground line A and its lower end.Qextended'sslightly @below they normal level ,1 of .they liquid' in tank7 tight joint therewith and has its upper end as determined by a suitable overflow tube7 presently described. y

In like manner thelower end of the drop tube extension 2* extends below the normallevel of the liquid in the tank to form a liquid-seal therewith.

The bottom of the outer end of the tank *1* is provided with an outlet .tube *5* having its upper end extended slightly abovey against vthe upper end ot the outlet tube,

*5* but may be opened at will in a manner presently described.

'The outlet tube *5* and overflow tube 9* are `arranged in vertical alinement with the Vinterior ot the manhole tube The upper end of the overflow tube *9* terminates some distance below the top of the tank *l* but above the lower end 01": the manhole tube*4* when the overflow tube-is in its lower-most position to close the valve 8* thereby determining the level ot the liquid within the tank. I

An operating rod or stem *10* is eX- tended centrally through the overflow tube *9* and has its lower end pivotally connected by a pin *l1* `to the corresponding end of said overtiow tube and its upper end extended into themanhole tube *fland Vpivotally connected at *12*v to across bar 13*. l V Y.

This cross bar *13* extends diametrically across theinterior ot the upper end ot the manhole tube .-*1* and is removably and pivotally a'ttacl'ied at both ends to suitable brackets *14* on adjacent sides of the manhole tube by means ot pivotal pins *15*. f o y The brackets *lei* aresecured to the 1nner sides ot thermanhole tube *Lland are f provided with a series 01"' apertures arranged in planes one above the other for receiving the pins *15* and thus permittmg the overiow tube *9* and .its valve *8* to be adjusted vertically to different positions Aas may be required to firmly close the valve *8 upon its seat.

The upper end of the manhole tube 4* is normally closed by a cover or cap plate 1(5* which is held in place by nuts *17* 'and bolts *l8 thelatter being secured to diametrically opposite sides ot themanhole .tube *llatl right angles tothe bar *13* to extend through registering apertures in the cap plate *16* where they are engaged by the nuts *17* to lock the cap kplate in its closed position and also to permit the removal thereof when it is desired to gain access to the interior of the vat.

\Vhen the capV plate *16* lis removed one or `the other or both of thepins *15* may be withdrawn by hand to permit upward movement of the bar *13* for raising the overflow tube *9* and thereby opening the valve *S* to allow the discharge of the material from the interior of the tank through the outlet *5* and thence to the drain pool, it being understood that the return of the bar 13* to its normal position will automatically lower the tube *9* and closethe valve 8*.

The `material deposited within the tank *1 may be agitated and thereby more or less liqueied by means of an agitatorl plateV 1Q-having an operating rod *20* eX- tendmg upwardly therefrom through a guide tube *21* 1n the top or" the tank 1* and. also through an opening in thel floor *F* adjacent the bowl O -where it is provided with a handle *20* for reciprocating the agitator v*19* vertically. rlhe guide tube *2l* is secured in an opening in the top wall of the tank `to form la Ygas-tight joint therewith and has its lower end extended slightly below the level ot the liquid'in the tank to term al liquid seal.

The upper .end of the guide tube *21* `extends some distance above the top of the tank and is provided with a suitable gland *22* for guiding the rod *20* inl its vertical movement and incidentally forming a gas-tight joint therewith.

It will be seen from the foregoing description that the lower ends ot each of the tubes *2* and *21* extend below the normal level of the top of the overflow tube *9* and, therefore, below the .normal level ot the liquid in the tank sov that the liquid may seal the open lower ends of saidtubes to prevent the escape ot vitiated air orgas therethrough.

vllicnever necessary or desirable the agil tator *19* maybe reciprocated vertically by means of its operating rod *20* for liquetymg` thesolids in the tank and permitting them to iow off through the overilow tube *9* and thence outwardly through the drainage pipe 6* as, soon as the level of the liquid rises to the level of the tube of the vovertlow tube.

l/Vhenever it is necessary `or desirable'to .drain the tank the cap plate *16 may be removed thus permitting access to the bar *13* and its retaining pins 15, either ot which latter may 'be Withdrawn to lpermit theV bary to be rocked upwardly about the other pivotal pin to raise the overflow tube 9* and-thereby open the valve 8* fori drainage purposes.. v

lt will be noted that the manhole tube -4- is of sufficient interior diameter to permit the overflow tube -9 and parts carried thereby to be withdrawn upwardly through the manhole tube to the exterior of the tank for repairs or replacements when desired.

That we claim is Y 1. In a chemical toilet, a receiving tank having a drainage outlet, an overflow tube within the tank communicating with the outlet for determining the level of the liquid in the tank, a toilet bowl above the tank, a drop tube leading from the lower end of the bowl and provided with an extension tube secured in an opening in the top of the tank and having its lower end extending slightly below the liquid level in the tank to form a liquid seal, a valve on the overflow tube controlling said outlet, said voverflow tube being movable vertically to open and close the valve, a guide tube secured in an opening in the top of the tank and having its lower end projecting slightly below the level of the liquid in the tank to form a liquid seal therewith, and an agitator reciprocally movable within the tank and provided with an operating rod extending through said guide tube and adapted to be operated by hand for reciprocating the agitator.-
